Abstract

Extra cation incorporations have been proved to enhance the properties of Cu₂ZnSn(S, Se)₄ materials, and help to obtain high-efficiency solar cells. In this work, the authors study the influence of the extra tiny Mg²⁺ doping on the properties of Cu₂ZnSn(S, Se)₄ films. Through tuning the amount of Mg into the precursor solution, the crystallization, morphology, light absorption, and electrical properties all have been improved and can reach the optimum at 3% Mg-doping, which is in favour of high-performance CZTSSe devices. The authors’ finding also demonstrates Mg element can be regarded as the new candidate for extra cation incorporations.

超细Mg2对Cu2ZnSn（S，Se）4吸收层性能的调控+

额外的阳离子掺入已被证明可以提高Cu2ZnSn（S，Se）4材料的性能，并有助于获得高效太阳能电池。本文研究了超细Mg2+掺杂对Cu2ZnSn（S，Se）4薄膜性能的影响。通过调节前驱体溶液中镁的含量，结晶、形貌、光吸收和电学性能都得到了改善，在镁掺杂3%时可以达到最佳值，这有利于高性能CZTSSe器件。作者的发现还表明，镁元素可以被视为额外阳离子掺入的新候选者。
